钢筋混凝土吊车梁钢筋疲劳可靠度分析

The Analysis of Steel Bar’s Fatigue Reliability of Reinforced Concrete Cranebeams

基于吊车载荷随机数学模型和钢筋的疲劳试验结果，进行了吊车梁钢筋的疲劳累积损伤概率分析。

In this paper,based on the random mathematical model of craneload and the results of steel bar’s fatigue experiment,the steel bar’s fatigue cumulative damage in reinforced concrete cranebeams is discussed.The analysis method is put forward for the fatigue reliability and fatigue life of the steel bar in reinforced concrete cranebeams.
